> The fix applied in CAMEL-16263 allows the SubscriberWrapper thread to recover
> from a retryable PubSub server error.
> However the PubSub client library retries only ABORTED, UNAVAILABLE, UNKNOWN
> errors by default.
> Proposed fix: add a component option to specify additional retryable error
> codes in synchronous pull mode.
> It is possible to configure custom retryable codes by using the method
> builder.pullSettings().setRetryableCodes() in SubscriberStubSettings.Builder
> Note: The default builder SubscriberStubSettings.Builder configures retries
> with exponential backoff (current default settings: retrying during 1 minute).
> In addition the loop in
> org.apache.camel.component.google.pubsub.GooglePubsubConsumer.SubscriberWrapper#synchronousPull
> ensures that the consumer will trigger a new request when the retries end,
> effectively retrying forever.
